A hovercraft takes off from a platform. Its height (in meters), x seconds after takeoff, is modeled by

h(x) = -(x – 11)(x + 3)

What is the height of the hovercraft at the time of takeoff?

For an experiment, a penny is tossed. at the same time, a spinner with 8 congruent sections numbered 1–8 is spun. how many possible outcomes are there for the experiment?

The general form of the quetion of a circle is ax^2+by^2+cx+dy+e=0 where a=b=0 if the circle has a radius of three units and the center lies on the y axis which set of values of a, b, c, d, and e might correspond to the circle

Through non-collinear points there is exactly one plane.
